Cisco 7942 + SIP provider

Hello!

Pouvez 7942 Cisco with Firmware SIP used as stand-alone SIP device?

I mean can it works with the SIP via NAT provider, as it can Cisco SPA 303?

There was a discussion about this before.

https://supportforums.Cisco.com/discussion/11955621/register-Cisco-phone...

There is however, no conclusion to it.

This discussion spoke here registration 7942 with Asterisk.

http://www.experts-exchange.com/networking/telecommunications/IP_Telepho...

As Asterisk is a 3rd party PBX, this shows that the phone CAN register with SIP firmware with a provider. However, you will have to work intensively with the vendor to achieve this.

For example, you must create a custom file cnf.xml for the phone to download. To do this, you will need to copy the configuration of the CUCM and then modify it according to your needs. Apart from this, the firmware files should also be located on the TFTP server that you're pointing to the phone.

Also, you must make sure that the provider is no mechanism on the side to block messages coming out from the phone at their end Packet Capture could help you here.

It is not a guarantee that it will work, but you can try it without a doubt.

Thank you

  • Cannot set Cisco SX20 - SIP Login and password

    Hello

    I have a problem that I can not set up login and password on the SIP profile 1 config page. Whenever I set up and refresh page, login and password is missing and diagnostics show error "401 Unathorized" which register to SIP Proxy (VCS).

    Software version 6.3.

    No idea how it install without factory reset?

    EDIT: I found that if I turn off the SIP protocol, set username and password, it is there. But as soon as I activate SIP back, username and password is missing.

    Hi Tibor,

    This is due to CSCuj48259. If you go into your system and your configuration mode set to OFF, it will solve the problem.

    This defect has not yet been solved, however she is addressed in a future release. I have

    f you run TC 6.2 or higher, you will have this problem if you have your configuration set to auto mode and auto-discovery of a fine return of provisioning succeeds but supplys a blank user name and password for your system. Also, if it is set to auto and DHCP option 150 is configured on this network, he will attempt to provision with CUCM which would clear these fields.

  • Driver of Cisco Telepresence - room LoopBack

    Hello world

    Is it possible to create a meeting room on Cisco Telepresence driver that will return the video to the appellant alone in the room? As the [email protected] / * / Cisco's Sip URI? (A kind of selfview room)

    Thanks for your help.

    It is possible to show only one participant connected to a MCU conference selfview, but not for telepresence Server conferences.  It comes without caring if the driver is involved or not.  The service provided by Cisco closure is obtained with the C40/60 endpoints where the audio and the video plays in a loop directly to the connected call (output HDMI to HDMI-in, output audio RCA audio-in RCA/RCA).

  • [SPA3102] SIP recording every hour with the 401 error and directly 12 OK

    Location: INET-ADSL modem in bridge mode-SPA3102.
    Problem: not really, everything seems to work, can dial in and out.
    But...
    Because I'm curious, I have a logserver of installation and checked what happened every hour of registration.

    What I see in the syslog hourly the 3102 made re - enroll by the SIP provider, but first I think 401 Unauthorized een 12 error and measured, I see an OK message.

    @hw: thank you for your tip and your right on the spot!

    Never, ever, thought of this way of "logging" in a system and use delberatley an error response. With your tip, I thought that allows to read the RFC and found RFC 3665. This RFC describes the Protocol SIP basic call flow. And there he was, almost at the beginning of the real story on page 5! The protocol uses a command register which gives a message of 401 error back just to be sure to avoid security problems "man in the middle" (if I understand correctly). He present a challenge and you the answer to a totalizer new order including your answer on the challenge. Which will lead to an OK return the message.

    To resume: nothing weird, it is as expected. My curiosity is frankly satisfied. Another day with what I've learned something. Thank you.

  • How to replace the call number part on a SIP section if none is present

    Hello

    I have a 2821 router that is connected to a SIP trunk.  This router also has a PRI interface that is connected to a PBX Mitel.  The Mitel used the router has a primary connection to the PSTN.

    The Mitel will send the party call number most of the time, but sometimes it isn't.  All calls that are sent to the SIP provider without a party call number are deleted.  I don't know if can substitute part number calling using the command in clid on the Dáil peer, however is it possible only override the calling party number if I do not get one of the Mitel?  He got a number of appeal left like a DID I want to pass along in the SIP call.

    Thank you.

    You should be able to do it with a voice translation rule that matches an empty ANI.

    First rule to match a real number to a PBX, to adapt according to your needs. The second rule matches a null value and changes to 555666777, who adapt to what you would like to send to your phone company.

    How the DLINK has been configured for traffic between the site to site VPN subnets? You are able to add multiple remote subnets on DLINK? If you can, then you must add the pool of Client VPN subnet.

    Alternatively, if you cannot add multiple subnet on DLINK router, you can change the pool of Client VPN 192.168.6.0/24, and on the crypto ACL between the site to site VPN, you must edit the 180 existing ACL

  • SIP URI B2B calls via CUCM and Highway

    Hi all

    Cannot find out how to configure the SIP URI from SX codecs, recorded calls on CUCM.

    I CUCM and IM & P 10.5.1 a pair of X8.5.2 expressway with two areas of course - for B2B calls, and the external jabber.

    I want to make calls of SX-codecs outside via SIP, by using the URI field, for example, [email protected] / * / or [email protected] / * /. How can I configure that?

    I already have the routing model, which is the SIP Trunk for Exp - C, for H323 calls by ip address. Is it possible to make a routing model to call the SIP URI?

  • Client VPN sail to 10.0.0.0 when you are connected to the Cisco VPN

    I have a cisco ASA that provides access remote vpn for users. The address pool is 10.16.135.x. When a user (windows) connects to the VPN, a route to 10.0.0.0 255.0.0.0 is added to the routing table. If the private IP address of the user is in the 10.x.x.x range, the user can still connect to its local network. However, if the user has a remote site that also uses 10.x.x.x, the user is no longer able to connect to the remote site because of the 10.0.0.0 new road is added after the vpn connection is established.

    My RADIUS server is in place and respond to queries, but my router does not seem to be transferring applications to authenticate to it. In fact, when I connect to the router using HyperTerminal, it expires, and I find myself authenticate locally.

    I don't really like if my Cisco equipment authenticates with the RADIUS server, but I have to get set up to authenticate my users so that I can follow their time online. What I missed in my router configuration? Therefore no transfer requests to the RADIUS Server user authentication.

    Thanks for any assistance, you may be able to provide.

    If you explore the authentication Proxy and it works, it could make you forget the PPPoE fast enough.

    If you decide to pursue PPPoE, the following link is probably where you will find most of the information on the configuration of Cisco PPPoE:

    http://www.Cisco.com/en/us/Tech/tk175/tk819/tsd_technology_support_protocol_home.html

    "Providers" of Cisco forums could provide some guidance if PPPoE is achievable with your platform and environment?

    According to rfc

    If the Session time-out interval is too low for a proxy (i.e., lower)

    that the value Min - SE that the proxy would argue), the

    Proxy denies the request with a 422 response.  This response

    contains a header field in Min - TO identify the minimum session

    meantime, she is ready to support.  The UAC will try again, this time

    including the header of Min - SE in the query field.  The header field

    contains the largest header field Min - SE that he observed in all 422

    responses received previously.  In this way, the minimum timer meets the

    constraints of all proxies on the way.

    Response message 422

    If the value of the Session header expires is too small, the UAS or proxy refuses the call with a response message 422 Session Timer too small . With 422 response, the proxy or the SAMU message includes a header of Min - SE, indicating the value of minimum session, he can accept. UAC can then try again the appeal with a higher value of session timer.

    If a 422-response message is received after a GUEST query, the UAC can again INVITE him.

    There is two way to fix this

    1) asked the SBC (your SIP provider) the value change and the value of standards send the SIP invite session expires

    (2) change the value of the Min - SE on the CME on demand

    Run this Global Config on CME

  • PAP2T - calling for not having tone on incoming calls

    After several rounds of configuration, almost everything seems to work on my setup using the Cisco Linksys PAP2T-NA VoIP. The only problem that I face now is that anyone calling my number will not get a dial tone, even if my phone rings normally and if I have the phone, the call passes by normally pickup. But not having is not the tone on the side of the appellant sometimes makes them wonder if the call was successful, and then sometimes they will eventually cling.

    My SIP provider is justvoip.com and my DID is didww.com

    Anything else I should look?

    Thank you very much!

    Ricardo.

    The "target phone rings", also known as the "reminder" signal is sent into the goal of management-> caller.

    There are two basic types of message SIP world.

    The first (type 180) is just message - «target sounds» This type of signal wear no special tone. It is the appellant PBX (or phone same visitor) to play the sound signal.

    The second (type 183) message "I'll give you tones of progress to appellant by oneself." This type of signal begins one-way audio channel to the caller, tones of progress, including the ringing of waiting, can be passed trough it.

    The first type is preferred. The reminder signal is generated alongside the appellant - so the known caller signal is generated (also no bandwidth is consumed to complete). The second type is mainly used to transport non-standard signal, oral messages or so.

    To complicate matters, any PBX on the path can consider changing the message type 180 to 183 and vice versa.

    PAP2T responds 180 all the time. According to your description, it seems that someone considered as ask "I'll play the audio signals", but then it plays no signal. Or a person considered cutting the audio (not every operator allow audio to pass through its network beginning) but has not returned 183 message message 180.

    It may be your VoIP provider, it is the upstream provider, the provider carrying the call to PSTN, an operator of transit to the PSTN and same origin operator RTC on call side.

    Nobody will not disclose the path to the appeal to you - it is considered to be trade secret. And even if you know it, you are not eligible to call all operators asking them to do something. You have no business relationship for them, or you can provide details of calls (known for 'previous-in-path' operator only) for them.

    As I said in a previous comment - if the calling user is affected by a problem, then it must report it to their operator. This operator will review the question and ask the jump according to operator assistance if necessary. Same procedure is repeated until an operator at the origin of the problem will be reached.

    Well, you can complain to your carrier, but it is may not be able to help.

  • conecting the 7921g wireles phone to a srp527w?

    Hello

    Anyone know if it is possible to integrate a voip wireless cisco 7921g (sccp protoclol) with a small bussiness Srp527w (sip Protocol) gateway, even if if is by conecting another device (such as an access point) between the two? I know skiny is owned by cisco and sip is a protocol open source, so I don't understand why cisco does not implement the skinny Protocol in its Srp527w.

    Thank you

    Hi Javier, the reason is, most of the Cisco small business product line does not support exclusive protocols of Cisco with the exception of the CDP. 7921 phone is considered a "business phone" and is supported by Cisco TAC, not the HWC.

    ESP is considered a SAI that can register for analog phones to a SIP provider while also using local telco access integrated as a DSL termination and maintenance as a router.

    As mentioned previously, you should have no problem to wireless connect the phone to the RPS. But you will have problems using the signalling Protocol.

    Andrew Hickman has perhaps some information better than me. I'll hit up and see if there is a more clear information, better than what I provided.

  • Accidentally deleted network card

    I just bought the Cisco Linksys WRT54G2 provided with the Cisco Network Magic Pro. There is a map that shows every time that a new device connects to my router. Then I connected with my Ipod touch.
